I think the best names are the ones that got some personal touch and are related to what you wanna show...

People can throw some names into the ring but I think brainstorming about it and coming up with something yourself would be worth it, even if it takes a couple of days. Then you're also sure that it's not copy pasted from somewhere else and might already exist in a similar form.

Having your own name makes the blog more personal and you're more invested in it, you'll just have more fun working on it overall.
